Scorpio Tankers signs up for emulsion bunker fuel systems across entire fleet

FOWE Eco Solutions has entered into a memorandum of understanding with New York-listed shipping giant Scorpio Tankers to license FOWE’s emulsion bunker fuel systems for use on Scorpio’s entire fleet of over 100 vessels. 

Scorpio began testing FOWE’s emulsion fuel bunkers in 2022 and since December of that year has been continuously operating two of its vessels with 12% water emulsion bunkers. FOWE’s Cavitech device allows each vessel to produce emulsified bunkers onboard. Scorpio plans for all its vessels to be operating with this technology by the end of 2024. 

In December 2023 FOWE conducted tests on boilers at Alfa Laval to verify performance and emissions when combusting emulsified oil prepared with FOWE’s Cavitech device. The 15% emulsion showed potential improvement in average fuel consumption of up to 6%. 

Following this positive result, further testing was undertaken at Alfa Laval in January of this year to verify performance and emissions of a MAN 9L28/32 four stroke diesel engine. This involved a base test with standard fuel oil and a test with FOWE emulsified fuel with 12% water content. Each test was run at 50% and 100% load. The results noted that the 12% water content showed bunker savings of 8.7% at a 50% load and 6% at a 100% load. In addition, NOx emissions were lower on all load scenarios compared to the base test, with a 1.6% reduction at 50% load and 8.0% reduction at 100% load.
